being and constituting a part of this specifica tion.

It is well known that bristles are coated with small fibrous substances or beards, which flags o'r tops thereof. v

The nature of my invention consists in pro- "viding machinery bywhich this peculiar con formation of the bristle may-be used in separating and adjusting a disordered mass there-- of into two separate parcels, the flags of which, severally, shall all point the same way. To this end I construct a frame, as shown on Figure 4 of the drawings, the side beams of which are held firmly together by a central cross-beam. Near each end of said side beams I place rollers. (Marked A A'on Fig.1. The gudgeons of said rollers pass through said side beams, and on the front side thereof I attach the pulleys. (Marked B B on Fig. 4-.)

O G are pulleys, over which the same belts pass that move the pulleys B B. D D are cogwheels, in which the teeth of the worm-gears on the shaft E work.

E is a shaft with worm-gear working in the cog-wheels D D. This shaft has also a pulley, F, around which a belt passes, connecting it with the small shaft G, and working-the same, as hereinafter described. This shaft E is attached to the frame of the machine by two or more strong arms screwed to the front-side beam thereof, but extending upward and for ward to a sufficient distance from said side beam to afford room for the pulley-F to be rotated. This shaft E passes through said arms and revolves therein, as shown in Fig. 4 ofthe drawings.

The smallshaft G is attached-to said frontside beam by passing throughtwo upright arms attached thereto, and is revolved by a are pointed upward from the butts toward 'the' belt from the pulley on the shaftlil, asshown' I The arms I I are attached to the than by v the set-screws M M, and they are also conneeted with the oscillating shaft V by placing their opposite ends in grooves or lips extending from the front side, of the shaft -V, and fastening them therein by pins, on which they work, as shown at K K on thedrawings.

" P is a shaft, on the front end of'which is' one of the pulleys C, and one of the cog-wheels D, as above described. ()n' the opposite end of this shaft I attach a pulley, Q, which is connected bya belt with the large pulley R, here inafter mentioned. On the center of this shaft P, I fasten a grooved pulley, S, which is con! nected by a round belt running in its groove with another grooved pulley, S, on shaft T, hereinafter described, and working in'connection therewith, as shown by Fig. 3, The end of said shaft P, opposite the cog-wheels, but inside the pulley Q, rests, and revolves in a square variable box, (marked U,) which is set ina slot on an upright post attached to'the frame. This arrangement is made to allow the end of the shaft to raise or lower in proportion to the size of the mass of bristles that may be passed no dcr the said grooved pulley an d round belt, as hereinafter set forth. The centralportion of this'shaft P is made in a square form,

and is adjusted to the sizeof the opening in wheel is placed, rests on a bearing constructed asfollows," namely: I pass it through'a pivot-f 7 box, (marked 2,) which is held in'its place by a set-screw passing through anupright slot-j ted post on the frame of the machine. This device allows the opposite end of the shaftto' be'raised vertically to any desired altitude, and thereby regulates its position to the mass of bristles that may be passed under the pulley thereon.

The grooved pulley on said shaft is held securely in its place by clamps, which pass over each side thereof, and which are screwed down 'iirmly onits elongated sides.

The shaft T is constructed and adjusted in all respects like the shaft P, above. described, except that it has no pulley on the end thereof opposite the cog-wheel. It rests on a pivotbox, Z, and a variable, box, U, and has a grooved pulley, S, corresponding in shape and function to those above mentioned on shaft P, and in every particular these are duplicates thereof.

' V is an oscillating shaft, attached at its ends to the shafts P and T, and the same clamps which hold the grooved pulleys S S on said shafts serve to fasten it firmly to said shaft and said pulleys. Its movement is regulated by the length of the crank motion given to the arms I-I by the adjustment of the nuts N N, as above described, and, being connected with the grooved pulleys S S, it communicates the same motion to them which it receives from the armsI I. Y

The'large pulley R'is fastenedon a shaft secured to the under side of the frame. 0n thislast-mentioned shaft, near the center thereof, I attach alarge drum or wheel, so corrugated as to be adjusted to the anti-friction rollers, of an endless traveling platform, as shown in the drawings ate a on Fig. 4. It is connected with the pulley Q by a belt, which moves them conjointly, but is made large in order to give a slow movement to said drum. I also construct another'shaft and drum thereon, which I place at the opposite end of the frame, inside the supporting-pillars. This 'drum is likewise marked a a. the last-mentioned shaft by the action and It revolves with movement of the endless traveling platform, as'hereinafter shown.

W is an endless traveling platform, which passes around the drums a a, one of which it causes to-revolve, asabove mentioned, by its anti-friction rollers, which work closely in the corrugations thereof. It is constructed inthe usual form, with slats fastened together'by grooves and pins. At each end of the pins,

however, I attach anti-friction rollersto work in the corrugations of the aforesaid drums. I also fasten small strips near the center thereof,- on the outside, at such a distance apart as that they may serve as guides to a leathern belt which surrounds the" traveling platform and is held in position between said small strips. These anti-friction rollers are adjusted to the corrugations in said drums, and the plat: form is moved with the same rapidity as the drums around which it passes. Fig. 2 represents a section of this traveling platform,

Around the rollers A A, I place three endless belts, (marked Y-Y Y on Fig 1.) These pose setforth.

belts extend around the travelingplatform,

and make the entire circuit of the machine. The central belt of these'three runs in the grooves on said platform made by the small strips above mentioned, and passes immediate] y under the grooved-pulleys S Sand the round belt that runs in the same. Immediately above this-central belt andthe said round belt, and on the lower side of the oscillating shaft V, in grooves made therein, I place a series of small rollers, grooved or otherwise, on which the said round belt moves, and by which its vibratory motions are partially regulated. v

The mode of operating my said device is as follows, to wit I attach suificientmo tive' power to that end of the shaft E where the crank is placed in the drawings, Fig. 4.. As the power revolves thisshaft, the worm-screws thereon,

working in the cog-wheels D D, impart a rotary motion to the shafts 1? and T. The large I Now, as a crank motion is securedto the arms I I by a proper adjustment of the adjustable nuts N N, and from said arms communicated to the oscillating shaft V, it follows that shaft V, grooved pulleys SS, and the round, belt thereon, are made to oscillate sidewise with such speed of motion as I may require.

The'bristles to be separated are placed upon the three belts Y Y Y, and are carried thereby under the grooved pulleys S S and the round'helt thereon. The oscillating movement above mentioned of these pulleys and belt causes said belt to rub closely 'upon the beard of the bristles, and'thereby crowd them each way, the butts out-ward. After having passed the 'farthermost grooved pulley the bristles are taken off and are ready for use.

. What I claim as my invention, and desire to secure by Letters Patent, is-

1. The grooved pulleys SS and the round belt thereon, constructed and operated sub stantially as and for the. purposes specified.

2. The endless traveling platform W, with the anti-friction rollers thereon on the inside,

and the small guiding-strips on the outside, combined with the large pulley R and the v drums a a, substantially as. and for the pur- 3. The three belts Y Y Y, in combination with the traveling platform W and rollers A A, when constructed'and operated substantiallyas and for the purpose herein specified. 4. The shaft E and worm-gear thereon, in

combination with the cog-wheels D D and pulndless cirleys C O and F, substantially as and for the purpose set forth.

and set-screws thereto, substantially as and for the purpose set forth. 7

7. The entire machine, with its described devices, constructed and operated substan tially as and for the purposes speoiii m.
